1.) MAIN XLR INPUT (BAL/UNBAL). The system accept female XLR input connectors and line level signals from a mixing console or other signal source

2.) LINK XLR OUTPUT. The output XLR male connector provides a loop trough for speakers daisy chaining and crossover out if LINK/XOVER switch is pressed.

3.) VOLUME. Controls the volume of the power amplifier. The control ranges from - (maximum attenuation) to the MAX level (maximum output).

4.) POWER INDICATOR. Power on indicator. When the power cord is connected and the power switch is turned on this indicator lights green.

5.) SIGNAL INDICATOR. The signal indicator lights green if there is signal present on the main XLR input.

6.) LIMITER INDICATOR. The amplifier has a built in limiter circuit to prevent clipping of the amplifiers or overdriving the transducers. When the peak clipping circuit is active the LED blinks orange. It is okay if the limit LED blinks occasionally. If the LED blinks frequently or lights continuously, turn down the signal level. The amplifier has a built in RMS limiter. If the RMS limiter is active the LED lights red. The RMS limiter has the purpose to prevent damages the transducers. The speaker shall never be used with the limit indicator red, continuous operation with the RMS protection active can cause damages to the speaker.

7.) HIGH PASS. The switch gives the possibility to set high pass filter at 30 Hz or 45 Hz.

8.) LOW PASS. The switch gives the possibility to set low pass filter (crossover point) at 90 Hz or 140 Hz.

9.) PHASE. The switch gives the possibility to rotate the phase of 180° (phase reverse).

10.) LINK/XOVER. The switch enables the XLR link/xover output to daisy chain the signal or to add the crossover filter to the output signal.

- LINK (daisy chain the input signal).

- ON (add the crossover filter to the output signal).

11.) AC POWERCON RECEPTACLE. RCF D Line uses a POWERCON locking 3-pole AC mains. Always use the specific power cord provided in the package

12.) AC POWERCON LINK RECEPTACLE. Use this receptacle to link one or more units

Always make sure that the maximum current requirement does not exceed the maximum admitted POWERCON current. In case of doubt call the closest RCF SERVICE CENTRE.

13.) POWER MAIN SWITCH. The power switch turns the AC power ON and OFF. Make sure that the VOLUME is set to - when you turn on the speaker.

14.) FUSE.
